BURNISHING-MACI-IINE.

terial of varying shape, size and contour,.

such for example as vamps for shoes.

Its salient feature consists in providing a revolving burnishing tool orspindle op erating in connection with feeding mechanlsm.

Another feature consists" in providing a peripheral slot or groove insaid tool; into which the material to be burnished extends while saidtool is revolving. 7

Another feature consists in unique for heating the burnishing tool.

Its other features and advantages will readily become apparent from thefollowing specification. V

The base of the machine, in the present instance, consists of an oil boxor pan 1, on which is mounted at the top the upper plate 2 by means ofscrews 3 and 4, which plate has depending arms 5 and 6, fastened attheir extremity to a lower plate 7 by means of Screws 9. I 7 Upon theupper surface of plate 2 at its Specification of Letters Patent.

Application filed January 10, 1916. Serial No. 71,262.

'rear, we connect the upward 'andforward extending arm 10, by means ofscrews 12 and 13. In the forward end of said arm 10 we provide a screwthreaded bearing 14,

to admit the upper center screw15. On this screw 15, we place the nut16' which allows said screw to be 'lockedinto place.

In the lower plate 7 andin perpendicular alinement with the uppercenterscrew 15, we provide the lower center screw 17 which may be locked ifdesired, same as the upper center screw. 1 q

Between these two center screws 15 and 17, we provide and place thevertical revolv- 111g spindle 18 made up of parts which we will nowdescribe. The upper portion of spindle 18 consists of a cylinder 19cored out in its center to admit the heating unit 20; fastened to theupper face of said cylinder 19, we provide the housing 21, secured in.place by the screws 22 and 23;

between the housing 21 and cylinder 19, we

in itsupper position has .a centerbearin'g 25, which revolves aroundtheccnter screw 15;. the housing also, carries a cup 26 for carrying oilto lubricate the screw and'bearing, having a cap 27 the housing 21 hastwo outwardly extending arms 28 and 29, upon which we fasten the micapads 30 and 31, for insulation purposes, these pads being held inposition by screws .32; on top of the mica pads 30 and 31, we secure thetwo rings34' and 35 by means of screws 36 and 37, thusinsulating therings 34 and 35 from the'housing 21. Connected to the ring 34 isanelectric wire 38 and connected to the ,ring 35 is: a wire 39, thusforming a positive and negative connection to the electric unit, seeFig.8 particularly. Fastened to the arm 10, at point 40, we providecenter bearing 51, which revolvesaround the 7 center screw 17 Throughthe following means we revolve the spindle 18, to wit: In lower plate 7,we provide a bearing 52 and at the point 53, we fasten the upward andforward extending arm 54:, by means of screw 55. In the forward end ofarm 54: is a bearing 56 in perpendicular alinement with the bearing 52.We provide a perpendicular shaft 57 revolving in the bearings 56 and 52,and on shaft 57 We fasten the gear wheel 58 which meshes with the gearwheel 50 on spindle 18, thus revolving said spindle. On the upper end ofshaft 57 we place the miter gear 59. On a horizontal shaft 60 in bearing61 on plate 2 and bearing 62 on the depending arm 5 and bearing 63 ondepending arm 6, we place the miter gear 64: which meshes with mitergear 59 on shaft 57, thus imparting motion to said shaft 57. On theshaft 60 we place a pulley 65. On this same shaft 60, at its forwardend, we place a gear wheel 66. In the depending arm 5, we place a stud67 which is locked into position by nut 68. The lower feed roller 69revolves on the forward end of the stud 68, and fastened on the hub endof said feed roller 69, we place the gear wheel 70 which meshes withgear wheel 66 on shaft 60, see particularly Fig. 7, and thus driving thelower feed roller.

To arm 10 we connect the forwardly and downwardly extending arm 71, bymeans of screws 72 and 73. Said arm 71 also extends around the spindle18 as shown in Fig. 6.

. In the forward end of arm 71, we place a sliding bearing 74 so thatthe upper feed roller 75 can move up and down. In the sliding bearing74, we provide the bar 76 which, at its lower end, extends forward andthus supports and holds the stud 77 on which the upper feed roller 75revolves.

The bar 76 is held in position by means of the straps 78 and 79. Adownward pressure is exerted upon the roller 75 through means of spring80, which is connected at its lower end at point 81 on strap 79 and atits upper end is connected at point 82 to bar 76.

In the spindle 18, we place a peripheral slot 83 of any desired size andcontour. It will be noted that the spindle or burnishing tool 18 extendsthrough plate 2 as does also the lower feed roller 69. The feed rollers75 and 69 feed the material and hold it in place in the slot 83 in therevolving spindle 18, said feed rollers being so placed that thematerial to be burnished can readily be fed into the slot 83. 7 g 7Through the mechanism described the burnishing tool, which is thespindle 18, revolves in the same direction as the feed of the material,the best results are obtained however by driving the spindle or burnishing tool considerably faster than the feed of the material.

It will readily become apparent that this machine can be operated veryrapidly and continuously and the burnishing can be done uniformly andevenly.

From the above description it will be seen that the improved burnishingmachine, con-' also be obvious from the above description that theburnishing machine is capable of considerable modification, withoutmaterial departure from the principle and spirit of the invention, andfor this reason'we do not wish to be understood as limiting ourselves tothe precise form and arrangement of the several parts of the device asherein set forth in carrying out our invention in practice.

4. In a burnishing machine, a revolving spindle carrying heating meanswithin it and provided with a peripheral groove constructed and arrangedto receive the edge of the material to be burnished, and feeding feedingthe material through said groove in the same direction as the surface ofthe spindle at the point of contact with the material, the revolvingspindle having a surface speed faster than that of the feedingmechanism.

6. In a burnishing machine, a hollow re- 1.30

volving burnishing tool carrying an electric heating unit Within it, andmeans for transmitting the current to the said heating unit as theburnishing tool is revolving, saidtool provided with a peripheral grooveconstructed and arranged to receive the edge of the material to beburnished, and means for feeding the material into and through saidgroove.

7. In a burnishing machine, a revolving spindle formed of an upper and alower part suitably joined together and supported between upper andlower center bearings, said spindle carrying heating, means within itand provided with a peripheral groove constructed andarranged to receivethe edge of the material to be burnished, and means for feeding thematerial into and through said groove.

8. In a burnishing machine, a revolving burnishing tool provided with aperipheral groove constructed and arrangedto receive the edge of thematerial to be burnished, said tool carrying an electric heating unit,and means for feedingthe material to and through said groove. i

9. In a burnishing machine, a vertically disposed and suitably supportedrevolving spindle, a heating unit within said spindle for transmittingheat thereto while the same is revolving, said spindle provided with aperipheral groove constructed and arranged to receive the edge of thematerial to be burnished, and means for feeding the mament and a heatingelement'combined to-- gether to form a single'revolving tool, said 7tool having a peripheral groove constructed and arranged to receive theedge of thematerial to. be burnished.

11. In a burnishing tool, a burnishing element and a heating elementcombined together to form a single revolving tool, said =tool having aperipheral groove constructed and arranged to receive the edge of thematerial to be burnished, and means for feeding the material to beburnished to and through said groove.

12. In a burnishing machine, a revolving spindle carrying heating means,and provided with a peripheralgroove constructed 7 and arranged toreceive the edge of the material to be burnished, and means for feed ingthe material through said groove, the revolving spindle having a surfacespeed faster than that of the feeding mechanism.
